The aim of the study is to clinically evaluate the performance of S-PRG based \& Alkasite based resin composite restorations versus conventional resin composite restorations after caries control in Class I carious cavities in posterior molar teeth over 1 year follow up.
Traditionally, less conservative methods have been employed to treat tooth decay, which implied more loss of healthy dental tissue in order to increase the mechanical retention of the restorative material. Minimally invasive treatments have been proposed as an alternative therapy, which has evolved in with the development of new biomaterials.Bioactive restorative materials, as advocated by the FDI World Dental Federation, can promote mineralization/hard tissue creation, bacterial infection control, inflammation prevention, and tissue regeneration. In simpler terms : One efficient way to achieve bioactive functionalities in dental materials is to use particles that have the ability to release particular component.The development of "Giomer" based resin composites, which have the added benefit of prolonged fluoride and other ions release as well as rechargeability, is one of the key technological advances in resin composites to promote its usage as a bioactive material.In fact, Giomers with S-PRG fillers can release more fluoride than that of other fluoride-releasing restorations.Acid neutralization capacity by S-PRG fillers, one of many bioactive functions, is in which the pH of the surrounding environment became slightly alkaline upon contact with water or acidic solutions, exhibiting a modulation impact on acidic circumstances. Owing to the release of multiple ions, such modulation effect might be brought about by the release of Sr, B, Na, and F ions clarifying an acid buffering mechanism.A modification of GIC is Cention-N, which was introduced as a new resin-based material containing alkacid fillers, such as fluoride, calcium, and hydroxide ions, to neutralize acids. Owing to being tooth-colored, inexpensive, and having good flexural strength, It's considered as a subcategory of the composite material class.With properties similar to those of GICs and RBCs, Cention-N releases calcium, hydroxyl, and fluoride ions to prevent tooth demineralization. The presence of hydroxide ions on the material's surface may be crucial in neutralizing the acids that were produced by cariogenic bacteria Additionally, the filler's release of calcium and fluoride ions contributes in remineralization process.In Conclusion; S-PRG \& Alkasite based composite restorative materials are able to release ions that contribute to tooth mineralization as well as have a modulation effect on the acidic conditions produced by oral cariogenic microorganisms.

A fluoride releasing, highly aesthetic dental material that is S-PRG (Surface Pre-reacted Glass Ionomer) based , has the ability to recharge fluoride and appropriate for patients with a high caries index.
Cention N offers tooth-coloured esthetics together with high flexural strength. The new filling material belongs to the materials group of Alkasites. The patented alkaline filler increases the release of hydroxide ions to regulate the pH value during acid attacks. As a result, demineralization can be prevented. Moreover, the release of large numbers of fluoride and calcium ions forms a sound basis for the remineralization of dental enamel. The initiator system enables good chemical self-curing.
